【Abstract】 The problem of H_∞ robust and resilient control for a class of singular interval systems with state delay is proposed.The purpose of the H_∞ robust and resilient control is to design a state feedback resilient controller such that the resulting closed-loop systems are robust stable with H_∞ norm bound.Two classes of perturbations are considered, namely,additive and multiplicative.This problem is solved via the notion of generalized quadratic stabilization with H_∞ norm bound.And the resilient controllers can be obtained by solving a set of linear matrix inequalities(LMIs).An illustrative example is given to demonstrate the effectiveness of the design method proposed.更多还原
